If you’re in the world of IT, you’ve probably heard of SSH. It stands for Secure Shell and is a network protocol that allows you to securely access remote servers over an unsecured network. SSH provides a way to connect and communicate with your servers, execute commands, transfer files, and perform other administrative tasks. While SSH can be powerful, it can also be challenging for beginners to use, especially when dealing with multiple servers. That’s where Juice SSH comes in. In this comprehensive guide, we’ll explore how to use Juice SSH to securely access remote servers.
Prerequisites
Before we dive into the details, let’s talk about what you need to get started. First, you’ll need an Android device as Juice SSH is an Android app. You can download it from the Google Play Store for free. Once you have Juice SSH installed, you’ll also need the following:
1. A remote server: This can be a virtual private server (VPS), a cloud server, or any other server that you want to connect to remotely. Make sure you have the necessary login credentials for the server.
2. Internet connection: Since Juice SSH relies on network connectivity, you’ll need a reliable internet connection to establish a connection with your remote server.
3. Basic knowledge of SSH: While Juice SSH simplifies the process, having a basic understanding of SSH concepts will be helpful.
With these prerequisites in place, let’s move on to the next section, where we’ll explore the features and benefits of Juice SSH.

1. Connection Name: Give a name to the connection profile for easy identification.
2. Hostname or IP: Enter the IP address or hostname of the remote server you want to connect to.
3. Port: Specify the SSH port number of the remote server. By default, SSH uses port 22, but it can be different based on your server configuration.
4. Username: Enter the username for the remote server.
5. Authentication: Choose the authentication method. You can either use a password or public-key authentication.
Step 4: Save the Connection
Once you have entered the connection details, tap on the “Save” button to save the connection profile. You’ll now see the connection listed on the main screen.
Establishing a Connection
Now that we have set up a connection profile, let’s establish a connection to the remote server. Follow these steps to connect:
